    The AESA functionality allows the array to be spilt into a half dozen or more smaller virtual arrays, each operating independently. For example, instead of one beam scanning through a 120 degree x 120 degree sector, you have six virtual arrays scanning 60 degree by 40 degree sectors. Then you sum the six sectors.

    These thin beams are working in conjunction with the ALR-94 too. Unless the enemy is flying EMCON, then the APG-77 will know where to look.

    Yes a single F-22 can take a ‘passive’ shot using ‘just’ information for the AN/ALR-94. Other aircraft claim to be able to do so as well (Rafale fans are particularly vocal). But again doing so is going to have a significantly lower pk than a proper lock.

    I don’t doubt it, but…..was just being conservative.:D

    700 NM is better, but not that impressive either, as we are talking about a clean fighter with 8,3 tons of fuel!

    Nic

    It exceeds 700nm, with 5500lb combat load on internal fuel, and >900nm with EFTs.

    True but in the beginning you’re going to go at pre planned targets most of the time. Unless you like to attack a country without knowing where they stationned their SAMs and other vital assets. I also doubt the JSF is going to be able to roam freely at their altitude of choice, because low band radars are going to detect them and fighters/other sensors can then be directed at them if they are detected at all.

    Nic

    Low band radars would be high priority targets for both kinetic and non-kinetic strikes, which is frequently ignored in these discussions.

    You can question it all you want it’s good until you pretend that I said a Rafale would be better at it than a F35.

    Anyway the Rafale is optimised to fly nap of the earth profiles at high speed with both a terrain following radar and an autonomous GPS/INS digital terrain following system. Combined with the impressive spectra EW suite, it should definately be enough to come in the range of the Scalp EG which is a stand-off stealthy cruise missile that is going to be used to dig a hole in the enemy IADS. All the while Spectra is going to provide ELINT/SIGINT for the next step.

    Then 125 kg AASM (125kg for added standoff range) are going to be used for DEAD to eliminate the rest of the enemy air defense from stand off range. Those could be targeted by spectra directly or by information from other Rafale’s spetra’s singint/elint capabilities.

    Nic

    Flying nap of the earth, means that you have much less situational awareness though, especially if you’re looking for moving targets.

    The more you are going to add weapons externally the shorter the range. If you add 6 tons of weapons to your beloved F35 the range will be cut dramatically from the 700NM maximum on internal fuel. Its exactly the same thing as removing external tanks from the Rafale to add weapons instead.

    Nic

    If you added external weapons, you’d also add EFTs.:rolleyes:

    It could carry a billion tons for all I care, what counts is the combat radius at a similar payload.

    F-35A:600 NM/1,100 km (AIM-120*2 + 2,000 Ib JDAM*2) as per toan’s figures is definately nothing spectacular for a plane that flies “clean” and that carries that much fuel! The fuel costs alone for any F35 user are going to be huge, especially when we consider 98% of the flights are going to be peacetime but operators are going to pay for that drag anyway while other aircrafts could do training missions with say 1 supersonic belly tank.

    Nic

    600nm was KPP. The F-35 exceeds this figure by >100nm.

    Sure the the F-35 is at the hight of 70th designs.
    But some Eurocanards reach ~7g at Mach 1.5 without speed loss.;)

    Let’s compare the numbers of the F-35 at those speeds then, and then we’ll have an apples to apples discussion.

    yet irrelevant when judging performance of fighters that entered service over 30 years later, except if these fighters do worse, of course

    No, a combat loaded F-35 compares with a clean fighter, was the point being made.

    er, do you mean that your performance benchmark is a fighter model that flew back in 1980?

    Combined with superior survivability/situational awareness, which is conveniently left out. All of the naysayer’s arguments rely on the fact that WVR performance is the only metric being used for comparison.

    A F35 can’t even carry internally the loadout that the Rafale carry in Afghanistan!

    Nic

    For Afghanistan, an F-35 wouldn’t have to limit itself to an internal load. What kind of load can the Rafale carry on the first day of war, when penetrating airspace protected by S-300/400s. Oh wait, it can’t penetrate that airspace.:D

    This is doubtfully with a T/W of 0.84 to 1.04 and only Mach 1.67 for a F-35A.
    A sustained turn capability of 4.95g at Mach 0.8 and 15,000 ft is not really good.:rolleyes:

    Not accurate. It’s interesting how you cherrypick numbers that you like, but when other charts from the same organization/company show different figures, you have selective memory.

    What average RCS? What exactly should that be?

    All those supernatural figures given for F-35, F-22, B-2 etc. given here are provided as frontal aspect RCS, I don’t remember having seen any frontal average RCS claims. Before we make comparison, we should at least make sure we compare comparable.

    BTW, would you be so kind as to post some link leading to that document? I would like to read it, maybe there is some explanation to that.

    Are you being purposefully difficult? Whenever you see RCS figures listed, it’s gonna be the frontal aspect. If you tried to provide figures for every conceivable aspect, it’d be a pretty cumbersome list. The point of the matter is that when an aircraft is inbound, the aspect that the enemy will see is the front, till the aircraft is over the their territory.

    ETs can be dropped if needed.

    Nic

    I hope there’s a tanker nearby, if you haven’t already used that fuel.:rolleyes:

    Each T/R module sends a ping at a certain frequency… at what amplitude?

    As I said before, power is a function of the amplitude squared (at a given frequency).

    No power = no range.

    That is a fundamental issue you have yet to explain the solution to.

    [Of course, there are ways and means, but you have yet to explain them – then you have to explain how you hide the characteristics of the solutions to limited power from a modern RWR]

    It’s already been explained to the extent it can be without going into classified techniques. Rapid change of freqs and PRF waveforms(and multitudes of simultaneous beams with all of these characteristics), very narrow beams(i.e. 2 degrees by 2 degrees or less), lower power, etc…
